Asymmetric capsular ring for inhibiting capsular opacification

1. A capsular ring for insertion into a capsular bag of a patient's eye, the capsular ring comprising:

an anterior ring defining a first opening and having a first cross-sectional width;

a posterior ring defining a second opening and having a second cross-sectional width, wherein:

a diameter of the first opening is greater than a diameter of the second opening; and

the second cross-sectional width is greater that the first cross-sectional width; and

a sidewall connecting the first ring and the second ring, the sidewall comprising a plurality of orifices spaced circumferentially around the sidewall.

2. The capsular ring of claim 1 , wherein at least a portion of the capsular ring is constructed from a self-expanding, biocompatible material.

3. The capsular ring of claim 1 , wherein:

the anterior ring comprises a first outer diameter;

the posterior ring comprises a second outer diameter; and

the first outer diameter is the same as the second outer diameter.

4. The capsular ring of claim 3 , wherein the first outer diameter and the second outer diameter correspond to a diameter of an equatorial region of the capsular bag of the patient's eye.

5. The capsular ring of claim 1 , wherein the sidewall comprises a flat outer profile.

6. The capsular ring of claim 1 , wherein the sidewall comprises a concave outer profile.

7. The capsular ring of claim 1 , wherein the anterior ring comprises a rectangular cross section having the first cross-sectional width.

8. The capsular ring of claim 1 , wherein the posterior ring comprises a rectangular cross section having the second cross-sectional width.

9. The capsular ring of claim 8 , wherein the posterior ring further comprises one or more bumps on its anterior surface.
